Description

  The present invention is a method for operating a sheet press having a sheet guide module that can be removed from the sheet press and then reinsertable into the sheet press, and a machine controller. And such a sheet-fed printing press for carrying out this method.

  Patent Document 1 describes a sheet-fed printing machine including a sheet guide module that can be taken out for cleaning purposes and other maintenance purposes. The sheet guide module is arranged next to the sheet transport cylinder and serves to guide the printed sheet conveyed by the sheet transport cylinder. When the sheet guide module is inserted again into the sheet press after maintenance, it is absolutely necessary to prevent incorrect positioning of the sheet guide module. This is because, as a result of incorrect positioning of the sheet guide module, there is a risk that the corresponding sheet guide module and the sheet transport cylinder collide as soon as the sheet transport cylinder starts rotating. Such a collision can lead to serious machine damage. The sheet guide module comes with a device that guides it during installation, and with the assistance of such a device, the handling of the sheet guide module is much more reliable than without it. Although possible, the installation failure cannot be completely eliminated with this device alone, i.e. without other safety measures. For this reason, the patent document cited above, which is also the applicant, allows the assembler to perform maintenance work associated with the removal and re-installation of the sheet guide module according to the commission from the printing factory. It has been a practical method that has been successful so far by applicants and manufacturers of the described sheet-fed printing presses. Such manufacturer's assemblers are particularly trained in the work of removal and re-installation and are very skilled in such work. However, there has been a long-standing demand from the printing factory side to let its operators perform such maintenance work. Even if the printing plant operators have been trained in the necessary installation work, they are performing maintenance work at various printing plants and are therefore far more frequent than those performed by individual printing plant operators. Since the level of proficiency of the assembler in charge cannot be reached, the applicant and the manufacturer listed above are safety measures, and only the in-house assembler is responsible for the maintenance work associated with the removal and insertion of the sheet guide module. It has traditionally been decided not to give the operator authority. In such a way, although sufficient installation safety was ensured, the printing factory's request to carry out maintenance work independently could not be met.

In order to solve the above-described problems, Patent Document 2, Patent Document 3, and Patent Document 4, which merely represent the related art that is not related, have not been able to make effective contributions.
German Patent Application Publication No. 199114178A1 German Patent Application Publication No. 10100197A1 German Patent Application Publication No. 10060557A1 German utility model specification 29710252U1

  Accordingly, it is an object of the present invention to provide a method for operating a sheet-fed printing press and a sheet suitable for carrying out this method, which allows risk-free maintenance of the sheet guide module by a printing plant operator. To provide a leaf paper printing machine.

  This object is achieved by a method comprising the features of claim 1 and by a sheet-fed press comprising the features of claim 12.

The method of the present invention for operating a sheet press having a sheet guide module that can be removed from the sheet press and then re-insertable into the sheet press and a machine controller is as follows: The position of the sheet guide module is monitored with respect to the correct operation position by the machine control unit, and the sheet is detected when the sheet guide module is at the correct operation position based on the position monitoring result by the machine control unit. A second operation mode having at least one operation function restricted as compared to the first operation mode when the printing press is maintained in the first operation mode and the sheet guide module is outside the range of the correct operation position. Chi coercive, said restricted operating function is characterized in that an operation function of preventing damage to sheet-fed printing machine.

  Configured to carry out the method of the present invention, having a sheet guide module that can be removed from the sheet press and then reinsertable into the sheet press, and a machine controller In the sheet printer according to the present invention, the position of the sheet guide module is monitored by the machine control unit with respect to the correct operation position, and the sheet guide module is detected by the machine control unit based on the result of the position monitoring. So that the sheet press is kept in the first operating mode when the is in the correct operating position, and is kept in the second operating mode when the sheet guide module is outside the range of the correct operating position. The control unit is connected to the sheet guide module in terms of control technology, and the machine control unit is configured such that the second operation mode is limited with respect to at least one operation function compared to the first operation mode. It is characterized in that there.

  In accordance with the present invention, positioning errors that may occur during the semi-automatic or in particular manual re-installation of the sheet guide module are detected by the machine control. For example, the machine control unit recognizes that the operator does not lock the sheet guide module to the holding device provided to hold the sheet guide module in the operating position. When such a fault occurs, the machine controller will determine the possibility of operating the sheet press, i.e. its function, until the fault is removed and the sheet guide module is in its correct operating position. Automatically limit gender. By limiting the possibility of operation in this way, erroneous operations that would lead to machine damage are inevitably performed. Thereby, maintenance and cleaning of the sheet guide module can be left to the printing factory itself.

  According to the present invention, when a sheet printer is switched on by a machine controller, which may be an electric or electronic structure, the operation that the sheet guide module requires for the printing operation. It is continuously checked whether it is in position. When in the operating position, the machine control automatically switches to the first operating mode or maintains it when already in the first operating mode. Otherwise, if at some point the machine controller recognizes that the sheet guide module is not yet in the required operating position or is no longer in the required operating position, based on sensor or circuit engineering, Automatically switches to the second operating mode, or maintains it when already in the second operating mode. Restricting one or more operating functions of the second operating mode as compared to the first operating mode can be limited locally or can be done to a different extent locally. . The extent of the restriction can be determined according to the proximity of the operation site to be restricted or the spatial relevance to the potential danger area, that is, immediately around the sheet guide module in this application. . For example, in the second operation mode, the machine control unit may be configured in the first operation part that is closer to the sheet guide module than the second operation part, or around the sheet guide module and in some cases. In the first operation part where the leaf paper guide module itself can be seen better than the second operation part, it is possible to allow the operator to perform more operations than in the second operation part. In the first operating mode, all possibilities of operation of the second operating part may be given again to the operator indefinitely. As a result, in the first operating mode, the machine controller controls each other in both operating parts. The same operational possibilities are given.

  The sheet printing press according to the invention is preferably a rotary printing press, so that the substrate paper to be processed internally is printed according to the offset printing principle and / or according to the flexographic printing principle. Configured to work.

  Next, development examples of the present invention described in the dependent claims will be briefly described one by one.

  In one development, the first operating panel and the second operating panel of the sheet printing machine are located immediately around the sheet guiding module in the operating position, and in some cases the sheet guiding device itself, They are arranged relative to the operating position of the sheet guide module at mutual intervals so that the operator can better observe from the first operation panel than from the second operation panel. The first operating panel is closer to the operating position and / or the field of view to view the operating position is more open from the first operating panel than from the second operating panel. In other words, the operator must check whether the sheet guide module is in the operating position or what is happening around the operating position, for example that the sheet transport device with the sheet guide module is moving there. Can be inspected better from the first operation panel. In the first operation mode, the machine control unit keeps both the operation panels activated by the machine control unit, and in the second operation mode, the machine control unit at least partially hides the second operation panel. In order to be kept in an activated state, it is connected to each operation panel in terms of control technology. That is, in the second operation mode, at least one operation member of the second operation panel is switched to an invalid state by the machine control unit, and as a result, the operator erroneously selects the operation member temporarily stopped. Operation does not cause any reaction of the sheet press. In the second operation mode, it is preferable that a plurality or all of the operation members of the second operation panel are disabled by the machine control unit. Each operation panel may be a screen type keyboard (touch screen) or in particular a push button type keyboard. Instead of these operation panels, only one multifunctional operation member, for example, a joystick may be provided. One operation panel may be a central operation panel, and the other operation panel may be a distributed operation panel. In this case, it is preferable that the first operation panel is a distributed operation panel and the second operation panel is a central operation panel. The central operation panel may be a main control console attached to the sheet printing machine for its control, or may be a control console arranged in a sheet discharge device of the sheet printing machine. Each of the dispersed operation panels may be one of the operation panels arranged in each printing unit of the sheet printing machine. The first and second operation panels are preferably distributed operation panels arranged in different printing units of the sheet-fed printing press. For example, the first operation panel is configured as a first operation keyboard disposed in the first printing unit, and the second operation panel is configured as a second operation keyboard disposed in the second printing unit. It may be. The operation members of each operation panel, for example, the push buttons of the operation keyboard, are not absolutely, but may be arranged in a uniform mesh in close contact with each other. Such operating members may be distributed and arranged on the wall of the printing unit, for example, at different intervals.

  In another development, the machine control unit is maintained in a deactivated state in which the number of operation functions of the second operation panel is larger than that of the first operation panel in the second operation mode. For example, it is programmed or configured in circuit engineering. For example, in the second operation mode, the machine control unit keeps only one of the plurality of existing operation functions of the first operation panel activated, and at the same time, moves the second operation panel to the second operation panel. It may be kept in a completely deactivated state so that no one of the existing operation functions of the second operation panel can be activated by the operator. When only one first operation member is arranged instead of the first operation panel and only one second operation member is arranged instead of the second operation panel, the machine control unit makes the first In this operation mode, both the above-described operation members are maintained in an activated state, and in the second operation mode, the first operation member is activated and the second operation member is deactivated. Will be kept in the state. The same is true for one case where a single operation member is arranged instead of the first operation panel and there is a second operation panel including a plurality of operation members, or instead of the second operation panel. The other case where only one operation member is arranged and the first operation panel including a plurality of operation members is present also applies in a figurative sense.

  In another development example, an operation function called “Taste-Betrieb” or “Inching operation” (inching mode in English) is operated by the machine control unit in the second operation mode. It is intended to be activated by the member and kept inactivated by the second operation panel or operation member. Depending on the operation function of “inching movement”, the operator can operate a motor for driving a sheet transport device with a printing unit or a sheet guide module, a main drive motor for a so-called sheet printing machine, or in parallel with each other. A plurality of such motors operating in operation can be moved step by step during set-up and maintenance operations of the sheet-fed press. Each time the operator activates the operation function “inching operation” by the corresponding inching of the operating member, the motor or each motor rotates at a low speed determined by the machine control unit, and the rotation angle ( The step width is relatively small and is limited by the machine controller. The sheet transport apparatus driven by one or more motors also moves forward by a relatively small limited circumferential angle or rotation angle each time the operating function “inching operation” is activated. In order to position the sheet transport device to the required phase position for maintenance work and setup work, it is often necessary to perform the operation function `` inching operation '' several times in sequence, i.e. Multiple feed steps may be required. The operation function “inching operation” can include two partial functions, ie “forward inching” and “reverse inching” that can be selectively called by the operator. The paper conveying device can be moved in opposite feeding directions (circular or rotational direction). For these two partial functions, two different operation members attached to the operation function “inching operation” may be provided. For example, the sheet transport device may be a sheet transport cylinder, provided with a first push button for the partial function “forward inching”, and a second push button for the partial function “reverse inching”. It may be provided on the operation panel. In the example just given, each time the operator presses the first pushbutton, the one or more motors and the accompanying sheet transport cylinder are rotated clockwise by a small (positive) rotation angle. Each time the second pushbutton is pressed, eg for the purpose of correcting the cylinder orientation, it can also be moved counterclockwise by a (negative) rotation angle that also has a small angle. The above-mentioned sheet conveying apparatus is not only a sheet conveying cylinder, but instead may be a chain conveyor of a sheet printing machine, for example, a chain delivery, which circulates during printing operation.

  The next development is that the protective cover of the sheet-fed press is supported so that it can be adjusted to the closed position, in which the protective cover closes the machine opening of the sheet-fed press. It is said. When there is a protective cover in an “open” position where the protective cover does not close the machine opening, the sheet guide module can be removed from the sheet press through such a machine opening. In the development example described here, the position of the protective cover is monitored by the machine controller, and as soon as the position of the protective cover reaches the conclusion that the protective cover is outside the closed position range, The machine controller is connected in control technology with the protective cover so that the paper printer is automatically switched to the second operating mode by the machine controller. That is, opening the machine opening necessarily results in the machine control switching from the first operating mode to the second operating mode. Thereby, the operator calls when the protective cover is positioned away from the machine opening and when the protective cover is positioned toward the machine opening in the first operating mode and is in the closed position. It is not possible to call any operation function that is ready. The protective cover is preferably configured as a protective lid that is slidably supported, and the mechanical opening preferably extends substantially horizontally above the sheet transport cylinder.

  In another development, the machine controller is connected in control technology with the sheet guide module via an electromagnetic clutch that serves to monitor the position of the sheet guide module. The clutch member and a second clutch member adapted to the clutch member can be used. In the development described here, the first clutch member has a first electrical contact and a second electrical contact, and the second clutch member has a third electrical contact and a fourth electrical contact. The first electric contact is connected to the first signal line, and the second electric contact is connected to the second signal line. When both clutch members are combined or plugged together, the first electrical contact abuts the third electrical contact to conduct current and the second electrical contact conducts current to the fourth electrical contact. Abut. That is, the first and third electrical contacts together form a first set of electrical contacts, and the second and fourth electrical contacts together form a second set of electrical contacts. . When the first clutch member is a male clutch half (plug) and the second clutch member is a female clutch half (outlet or socket), the first and second electrical contacts are plugged in. Pins and the third and fourth electrical contacts are plug-in sleeves. In this way, the electromagnetic clutch which is a four-pole connector includes at least one other set of electric contacts or particularly another set of electric contacts in addition to each set of electric contacts described above. The second clutch member is attached to the sheet guide module and, together with the sheet guide module, is removed from the sheet press when the clutch members are disconnected from each other, whereas the first It is advantageous for the development described here that the clutch member remains with the signal line inside the sheet-fed press. This signal line serves to connect the first clutch member to the machine control unit in terms of control technology. Furthermore, important for the development described here is that the second clutch member continuously connects the third electrical contact with the fourth electrical contact, a Kurzschlus bridge or connection bridge that conducts electricity. It is having. The connection bridge may be, for example, a lead wire having one end clamped to a third electrical contact and the other end clamped to a fourth electrical contact. Similarly, the third electrical contact, the connecting bridge, and the fourth electrical contact can be made from the same material to form a single U-shaped part, for example. When the clutch members are connected to each other, the first signal line is short-circuited with the second signal line via the connection bridge, so that the machine control unit is informed that the sheet guide module is in the operating position. Current flows from the first signal line through the connection bridge to the second signal line. For example, because the sheet guide module has been removed from the sheet press, or because the sheet guide module is not properly installed in the sheet press, the sheet guide module is in its operating position. If not, the clutch members are not connected to each other or are not fully connected, in which case the first electrical contact abuts the third electrical contact and / or the fourth electrical contact As a result, the current flowing from the first signal line to the second signal line through the connection bridge is interrupted inside the electromagnetic clutch, and the machine control unit Recognize that the sheet guide module is not in the correct operating position.

  In another development, the sheet guide module is arranged substantially below the sheet transport cylinder, and the sheet guide module is connected to the outer circumference of the sheet transport cylinder or the gripping flight circle. It is configured in a curved state so as to extend in the longitudinal direction at substantially equal intervals. The sheet guide module, which is attached in the immediate vicinity of the sheet transfer cylinder, serves to guide the printed sheet conveyed by the sheet transfer cylinder during its transfer. So, to a minor extent, it can extend to enter one area of both upper quadrants of the sheet transport cylinder. In either case, the majority of the sheet guide module is below the sheet transport cylinder. The region of the sheet guide module near the front and / or rear edge when viewed in the sheet conveying direction may be curved away from the sheet conveying cylinder. In this way, a so-called sheet entry zone at the rear edge of the sheet guide module and / or a so-called sheet exit zone at the front edge is configured to gently draw an S-shape. It may be. The guide zone of the sheet guide module, which is between the entrance and exit zones, which is much wider than both edge zones mentioned above, is in each case the outer circumference or gripping of the sheet transport cylinder. It extends concentrically with the flying circle.

  In one development, the sheet-fed printing press may include an impression cylinder supported at the same height as one another and a sheet-conveying cylinder already mentioned several times. , And is supported in a state shifted relative to the impression cylinder in the vertical direction. The center and rotation axis of the sheet transport cylinder supported between the respective impression cylinders are preferably at a lower level than the center and rotation axis of the impression cylinder. The sheet transfer cylinder is immediately followed by one of the sheet transfer cylinders immediately after each impression cylinder, and the horizontal line where the center point or center axis of the sheet transfer cylinder is located is the center point or center of the impression cylinder. The connecting center line of the common center point, which is located lower than the horizontal line where the axis is located, and where the center point of the sheet conveyance cylinder and the impression cylinder described above is located, extends in a zigzag shape based on the position of the center point It may be one of a plurality of sheet transport cylinders, which are alternately arranged with the impression cylinders as viewed in the sheet transport direction, and which are particularly an integral multiple (such as 2 times) the size of the printing press.

  In another development, the sheet transport cylinder has an elongated cross-section, i.e. a cylinder cross-sectional shape that is significantly different from a circle. Such a barrel cross-sectional shape may be substantially oval or substantially rhombus. This development also includes a sheet transport cylinder that differs significantly from a circle only when the cylinder cross-sectional shape is set to a specific cross-sectional shape. Such a sheet transport cylinder can be referred to as a vario cylinder and has a variable cylinder cross-sectional shape, for example, it is set to be substantially circular for transporting paper sheets and circular for transporting paperboard sheets. For example, it can be set to be elliptical so as to be significantly different from.

  Another development to be mentioned here is that the sheet guide module is a blowing air nozzle and / or suction air nozzle and at least one blower for supplying the nozzle with blowing air and / or suction air (Ventilator) is included.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a sheet printer 1 in which printing units 2a and 2b each including impression cylinders 6a and 6b are arranged in a line. Alternatingly arranged with the impression cylinders 6 a and 6 b are a first sheet conveyance cylinder 7, a second sheet conveyance cylinder 8, and a third sheet conveyance cylinder 9. Each sheet transport cylinder 7, 8, 9 is arranged on the first gripping device 10 and its diameter to hold the sheet to be printed by the sheet press 1. And a second holding device 11. The gripper device 10, 11 moves along the gripper flight circle 12 when the corresponding sheet transport cylinder 7, 8, or 9 rotates. The cross-sectional shape of each of the sheet transport cylinders 7, 8, 9 is retracted from the gripping flying circle 12 along the cylinder-shaped major axis 13 between the gripping devices 10, 11, and as a result, On both sides of the cross-sectional shape, a substantially crescent-shaped free space 16 exists between the corresponding sheet transport cylinder and its holding flight circle 12.

  The cylinder connecting center line 14 where the center points of the impression cylinders 6a and 6b are located extends above the connecting center line 15 of the cylinders of the sheet transport cylinders 7, 8, and 9. The sheet transport cylinders 7, 8 and 9 are offset from each other so that a specific rotation angle difference always occurs between two successive sheet transport cylinders 7, 8 or 8, 9 with respect to the respective rotational angle positions. The sheet conveyance cylinder arranged behind the sheet conveyance direction is ahead of the sheet conveyance cylinder arranged in front of the rotation angle position occupied by the sheet conveyance cylinder. is doing. Between the rotation angles α and β of the cylinders of the sheet transport cylinders 8 and 9, the same rotation as that between the rotation angles β and γ of the cylinders of the sheet transport cylinders 7 and 8 with respect to the angle values and positive / negative symbols. There is an angle difference.

  Above each of the sheet transport cylinders 7, 8 and 9, there are a mechanical opening 18 and a protective cover 17 for closing it. The protective cover 17 is provided with a sensor 19 for monitoring whether the protective cover 17 is properly closed, for example, an electric probe. Below each of the sheet transport cylinders 7, 8, and 9 is a sheet guide device 24 that includes a first sheet guide module 25 and a second sheet guide module 26. The first operation panel 20, the second operation panel 21, the third operation panel 22, and the fourth operation panel 23 are in different printing units.

  During the operation of the sheet-fed printing press 1 performed from the first operation panel 20 through the operation panel when the protective cover 17 is open, the operator passes the second, third, Alternatively, it can be monitored by looking at the first sheet transport cylinder 7 and the sheet guide device 24 much better than is possible in the case of an operation performed from the fourth operation panel.

  FIG. 2 shows that the sheet guide device 24 includes an installation device 29 that guides the sheet guide modules 25, 26 to their correct operating position when reinserting them and then holds them. Is shown. Further, each sheet guide module 25, 26 is shown to have a nozzle face 28 with a nozzle 41 and a blower 27 that supplies suction air and / or blowing air to the nozzle 41. . Each blower 27 is attached to each of the sheet guide modules 25 and 26 below the nozzle surface 28, and for example, stains due to set-off printing ink or paper dust are removed from the outside of the sheet printer 1. When the nozzle surface 28 is to be cleaned, the blower 27 is temporarily removed from the sheet printer 1 together with the sheet guide module as a component thereof. An electromagnetic clutch 30 is attached to each of the sheet guide modules 25 and 26.

  FIG. 4 shows an example in which the electromagnetic clutch 30 attached to the first sheet guide module 25 is composed of a first clutch member 31 and a second clutch member 32. The first clutch member 31 has a first electrical contact 33 and a second electrical contact 34, and is permanently attached to the installation device 29, i.e., stationary to the machine. A first signal line 37 is connected to the first electrical contact 33, and a second signal line 38 is connected to the second electrical contact 34. The second clutch member 32 has a third electrical contact 35, a fourth electrical contact 36, and a connection bridge 39 that connects the third and fourth electrical contacts 35, 36. The second clutch member 32 is permanently attached to the first sheet guide module 25.

  FIG. 3 shows operation panels 20, 21, 22, 23, a sensor 19, a main drive motor 40 that rotationally drives the sheet transport cylinders 7, 8, 9, and first signals via signal lines 27, 28. The clutch members 31 are connected to the machine control unit 42, respectively.

  The electrical protection of the sheet guide modules 25 and 26 attached to the first sheet guide cylinder 7 and the sheet guide modules attached to both other sheet transport cylinders 8 and 9 will be described below. The first sheet guide module 25 will be described as an example.

  The electrical protection is performed by the machine control unit 42 inquiring the position of the first sheet guide module 25 by the electromagnetic clutch 30. If the first sheet guide module 25 is not in the prescribed position, the clutch members 31, 32 will necessarily be at least partially separated from each other, so that the electrical contacts 33, 35 attached to each other and / or attached to each other. The electric contacts 34 and 36 are separated from each other. As a result, the energization of the electromagnetic clutch 30 is cut off between the signal lines 37 and 38. Such interruption of energization is a signal that informs the machine control unit 42 that the first sheet guide module 25 is out of the range of the operating position as required for the printing operation. As a result of such signal interpretation, the machine control unit 42 switches the sheet-fed printing press 1 from the first operation mode to the second operation mode.

  In the second operation mode, the machine control unit 42 notifies the operator of a dangerous state on the one hand by an optical or acoustic warning signal, and on the other hand, at the same time, specifies the sheet printing machine 1. It is characterized by that the movement of For example, the warning signal may be displayed on the display of a main control console (not shown) in the center of the sheet printer 1, or the printing unit 2b that is the target of damage or removal of the sheet guide module. May be a flashing light or a flashing button. In the second operation mode, what movement of the sheet printing machine 1 is hindered by the machine control unit 42 depends on whether the protective cover 17 is open or closed.

  When the sensor 19 informs the machine control unit 42 that the protective cover 17 is closed, the main drive motor 40 cannot be operated from any of the operation panels 20, 21, 22, and 23. One sheet transport cylinder 7 cannot be rotated. That is, the first sheet transport cylinder 7 is in a state where the movement is completely stopped.

  Instead, when the sensor 19 informs the machine control unit 42 that the protective cover 17 is open in the second operation mode, the machine control unit 42 sends the operation panels 21, 22, and 23 to these operation panels. From 21, 22, and 23, the main drive motor 40 cannot be operated at all, and therefore, the first sheet transport cylinder 7 cannot be rotated and is in a “dead” state. Thus, the operator can, for example, bring the first sheet guide module 25 back into the proper operating position, or move the first sheet guide module 25 through the free space 16 and the machine opening 18 for maintenance purposes. In order to remove it from the sheet printer 1 for cleaning purposes, it is possible to work without danger in the region of the first sheet transport cylinder 7. Other persons who are not aware of the danger situation associated with the assembly work can never rotate the first sheet transport cylinder 7 through the operation panels 21, 22 and 23.

  Unlike the operation panels 21, 22, and 23, the first operation panel 20 in the immediate vicinity of the operator handling the first sheet guide module 25 is completely “dead” by the machine control unit 42. ”State is not set. That is, the operator can move the sheet printer 1 by a groping operation before and during the assembling work for the first sheet guide module 25. For example, it is left to the operator to adjust the position of the first sheet transport cylinder 7 to the rotational position shown in FIG. 1 by intermittently moving the main drive motor 40 forward and backward. In this rotational position, the longitudinal axis 13 of the torso section is oriented substantially vertically, so that first the second sheet guide module 26 and then the first sheet guide module 25 are moved first. The sheets can be sequentially taken out from the sheet printer 1 through a free space indicated by reference numeral 16 between the first sheet transport cylinder 7 and the impression cylinder 6a disposed in front of the first sheet transport cylinder 7. In this way, the machine control unit 42 keeps the first operation panel 20 and only the operation panel open to the possibility of operating the “scrubbing operation”. Other open operation possibilities are no longer open in the second operating mode. In other words, the operator can use only “hand-off driving”, which is an operation method that is not dangerous as such, and this is limited to the case where the dangerous part is in view at the site.

  Unlike the above description, in the first operation panel 20, in the second operation mode, only one operation member beyond the operation member necessary for the groping operation or the operation member necessary therefor is provided. It is also possible to make it operable with. This other operating member serves to respond to the machine control unit 42 that the sheet guide modules 25 and 26 have been completely removed from the sheet printer 1.

  Such an electronic acknowledgment is important in the following relationship. That is, not only the sheet guide modules 25 and 26 of the printing unit 2b but also the sheet guide modules of other printing units must be taken out from the sheet printer 1 in order. When the cylinder cross-sectional shape major axis 13 of the first sheet transport cylinder 7 is still in the vertical position, the cylinder cross-section major axis of the second sheet transport cylinder 8 is still such vertical. In order to be able to take out the sheet guide module attached to the second sheet transport cylinder 8 from the sheet printer 1, it is necessary to set such a vertical direction. . That is, in order to take out all the sheet guide modules attached to the sheet transport cylinders 7, 8, and 9, after the removal operation in one printing unit is completed, the removal operation in the next printing unit is performed. Before starting, it is necessary to rotate the sheet transport cylinder to the take-out position shown by way of example of the first sheet transport cylinder 7 in FIG. Since the angles α, β, and γ are different from each other, it is impossible to simultaneously direct the cylinder cross-sectional shape major axes of all the sheet transport cylinders 7, 8, and 9 in the vertical direction. After taking out the sheet guide module from each printing unit, the operation panel 20, 22, 23 next to the respective sheet transport cylinders 7, 8, 9 is used to take out the sheet guide module. A response is made for each printing unit individually.

  The storage of such a positive response in the machine control unit 42 can be requested again from the machine control unit 42 every time the sheet-fed printing press 1 is newly started. Assume that the staff has changed. Depending on the situation, it is suitable not only to temporarily store the acknowledgment by the machine control unit 42 but also to store it in the fixed storage device beyond that.

  The operation members necessary for the affirmative response may be provided not on the operation panels 20, 22, and 23 but on the central control console.

  As a result of the affirmative response, the sheet printer 1 can perform an automatic process such as cleaning of an inking device, an impression cylinder, and a blanket cylinder, and a plate change even when the sheet guide module is taken out. Therefore, it is possible to operate at a so-called creep speed. In certain cases, it is conceivable that the sheet-fed printing press 1 obtains unlimited functionality after a response, or even obtains unlimited functionality except for the “sheet feed on” function.
